A field experiment was conducted at Zonal Agricultural Research Station (ZARS), UAS, GKVK, Bangalore during 2018-19, to know the influence of foliar spray on growth, seed yield and quality of quinoa cv. 507740. The experiment was laid out in RCBD and replicated in three times with eight treatment combination, T₀-Control, T₁- GA3 @ 100 mg/l, T₂-boron @ 0.4%, T₃-urea @ 2%, T₄-ascorbic acid @ 50mg/l, T5-Moringa leaf extract @ 3%, T₆-DAP @ 2%, T₇-salicylic acid @ 5-10 mg/l at 45 DAS. The results revealed that Foliar spray of ascorbic acid @ 50mg/l45 DAS recorded maximum growth, seed yield and quality attributes viz.,plant height at 60 and at harvest (118.67 and 127 cm), total number of panicles per plant (9.67), productive panicles per plant (7.33), panicle length of main tiller (35.33 cm), seed yield per plant (153.33 g), seed yield per hectare (16.87 q/ha), 1000 seed weight (3.33 g), seed recovery (95.62%), seed germination (90.67%), mean seedling length (14.50 cm), mean seedling dry weight (16 mg),seedling vigour index I (1193), seedling vigour index – II (1457), EC (341.33µS cm^-1) and protein content (14 g) over control (96.67 and100 cm, 6.67, 4.00, 27 cm, 105.67 g, 12.85 q/ha,3.10 g,87.89%, 85%, 11.50 cm, 9 mg, 1004,729, 357 and 13 g respectively)
